this will pull back. stb did when it went from 25ish to about a dollar (mar/apr 2010).
it went more or less sideways for a while after that.
the 4 drills should take 2 or 3 months to complete at a guess so there is plenty of time for a pullback. it may not go sideways for long though.
i am looking at somewhere between 80c and 85c as a price that will do to get in.
